DISEASES OF THE SKIN. 



ward : first, five irrigations with a litre of sublimate solution at 

 2J per cent, at three days' interval ; second, a friction with carbol- 

 ated soap at 10 per cent. ; third, a new irrigation with sublimate. 

 The animal seeming to be cured, was sent home on the first of 

 February. Eight days later he was brought back with the pathog- 

 nomonic itching. Treatment : washing with carbolated soap ; two 

 frictions of carbolated glycerin at 20 per cent. ; frictions with car- 

 bolated liniment (carbolic acid, 100 grammes; alcohol, 600 grammes; 

 green soap, 750 grammes). On February 16th the horse appeared, 

 again to be cured and was delivered to his owner. On March 7th 

 the eruption reappeared. New treatment : Three frictions of 

 Vienna tar liniment ; application of carbolated alcohol upon the 

 most affected regions ; washing with a sublimate solution. The 

 patient seemed cured for the third time, and left the hospital on 

 April 24th. Six weeks later, mange appeared again and soon 

 radiated over a large surface of the integument; it disappeared 

 only after the use of lotions of sublimate solutions used repeatedly 

 for two months. This time the cure lasted five months. At the 

 end of this period no sarcoptes were found on microscopic exami- 

 nation, but the animal again began to rub and scratch himself. 

 The way he was kept, and the measures which were taken, permit 

 us to exclude absolutely the hypothesis of successive infections. 



A second horse, affected by generalized sarcoptic mange of 

 long standing, was treated for five months. Eleven irrigations 

 were made with a solution of sublimate, five frictions of carbolated 

 soap (5-12 per cent.), a friction of Vienna tar liniment, an appli- 

 cation of carbolated alcohol by means of a brush, and frequent 

 applications of balsam of Peru. A cure seemed obtained, but the 

 mange returned within four weeks. 



A third horse, which had been mangy for years, was cured 

 after a treatment lasting ninety-three days. During the first three 

 weeks, three tar applications were made ; as the condition showed 

 little improvement, daily washings with a sublimate solution were 

 resorted to for a period of six weeks (solution of 1-1 J per cent., 

 three litres daily); during the same period, daily lotions with Hager 

 liquor were made (carbonate of soda, 250 grammes; hydrochlorate 

 of ammonia, 60 grammes; water, 12 litres; carbolic acid and 

 glycerin, of each, 100 grammes), for the purpose of softening the 

 skin, which was dried up and stiff. Four months later this horse 

 was brought back in a mangy condition. The diseased regions
